15 E. The HTML / CSS question proved to be easier than last year when the format was slightly different. It was pleasing to see how many students could provide correct answers to question part (a) but it is to be noted that it was not as high as expected with only 60% providing hypertext mark-up language for part (a)(i). Part (b) proved to be a good discriminating question with students gaining the whole range of marks. The majority of students secured 3 or 4 marks out of the 6. Common mistakes included students not understanding the difference between an ordered and un-ordered list or just providing <p> and </p> for the list section. The marks had to be syntactically correct to be awarded. For example, #toptitle was not the correct answer for missing item 5 because the # is omitted from id selectors when the tag is referenced in the body section of the HTML. E2. Part (a) was answered well by students. Weaker students did not show the spacing that would be present between the block tags. Other students either numbered the list or did not place any bullet points on them and lost the ability to secure one of the marks. Students do need to be encouraged to produce neat diagrams and the labelling of blank spaces and hyperlinks makes the awarding of marks a lot easier. Describing the effect of the style rule in part (b)(i) had most students realising that the font would be changed to Arial and the text colour blue, but some forgot to link this either to the text on the web page or the <p> tag so it was not clear which text would be affected. The majority of students could correctly write color:green for part (b)(ii) but to then add in the other required elements was a slightly harder challenge. Not many students appeared to know the syntax for an ID selector. It was also surprising to see a few students drop marks by writing color:blue which demonstrates a poor reading of the question. E3. Question covered the HTML and CSS part of the specification and was asked in a different way for this paper. Students were asked to identify some constructs, rather than draw or code a web page. Students need to be careful that, when providing answers, they only include what is needed. When identifying a class tag, for example, providing.boldred{ color : red; font weight : bold} will not secure the mark as it is unclear which part of the answer is actually the class tag. Whether students fully understood the meaning of a monochromatic colour scheme was hard to identify. Many just wrote about it being black and white which was deemed to be insufficient for a mark. Of the students who did secure the mark, many correctly identified that a monochromatic colour scheme uses one main colour and shades of that colour. The use of the meta element tag appeared to be more well known than the previous question part. The majority of correct answers were concerned around the use of this element by search engines. In part (d) students found the LINK tag difficult to identify and complete. The part most students managed to answer successfully was the href section as this also occurs in other HTML tags. Whilst students might know about external style sheets it was clear that the HTML tag needed to perform this was not well known. Page 5 of 7

16 E4. This question was generally well answered. Parts (a) and (b) were very well answered by students, with part (c) being correctly answered by the majority. In question part (d), to gain the mark for the <h> tag students needed to identify clearly the text as larger by either labelling it as such or drawing it a lot larger than any other text. Labelling the text as just h is not enough to secure the mark. The majority of students missed scoring full marks as it was not clear that they appreciated how line spaces are formed when using block level tags. The hyperlinks were surrounded by <p> tags and the examiners were looking for clear evidence of spaces between the three links. E5. Part (a) asked candidates to identify what an intranet is and the most common answer of a private network managed to secure the mark. Good candidates gave a more detailed answer and included aspects such as sharing information. Candidates that wrote about a private Internet were not awarded the mark. Part (b) asked candidates to write the HTML code for a web page. It was pleasing to see how many candidates secured high marks for this question. Strong candidates clearly recognized the required HTML tags and set out the code in a very readable manner. It was clear that some candidates still do not understand all of the HTML tags mentioned in the Teacher Resource Bank material. Weaker candidates used <ol> rather than <ul> for the list and some struggled to use any HTML tags at all. A few candidates introduced CSS style rules correctly into their HTML and were awarded credit for this when appropriate. It is clear that a few candidates are confused about the role of CSS. These candidates attempted to use CSS elements incorrectly by simply placing them straight into the code instead of setting up a style section or using the style attribute option inside a HTML tag.
